About this study
Official title: A Placebo-controlled, Double-blind Phase I Study in Healthy Volunteers With IMP761, a LAG-3 Agonist Antibody
The goal of this clinical trial is to evaluate the safety and tolerability of single and multiple doses of IMP761 in healthy female and male volunteers aged 18-55 with no history of disease affecting the immune system or recent use of medication with effects on the immune system.
The main question it aims to answer is:
Read more
- if IMP761 is safe and tolerable as determined by assessing vital signs, emerging (serious) adverse events, electrocardiography, and clinical laboratory tests.
Researchers will compare IMP761 to a placebo (a look-alike substance that contains no drug) to see if single and multiple doses of IMP761 are safe and tolerable in healthy volunteers. Part B of the study also investigates the effect of IMP761 on the inhibition of the keyhole limpet haemocyanin (KLH) driven immune response compared with placebo.
Participants will:
- receive IMP761 or a matching placebo intravenously once in single dose (part A and B) and three times in multiple dose (part C) during a 4 day in clinic stay with 4-8 following visits.
- receive KLH challenge
- be monitored for up to 103 days after the first dose.
Read the detailed description
This is a first in human, randomized, prospective, single centre, double blind, placebo-controlled study in healthy volunteers. It consists of three separate parts (Part A, B and C) with different study designs.
The main objective is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single ascending dose (SAD) (Part A and B) and multiple ascending doses (MAD) (Part C) of IMP761 as assessed by:
- Vital signs
- Treatment-emergent (serious) adverse events ((S)AEs)
- Electrocardiography.
- Clinical laboratory tests
- Laser speckle contrast imaging (LSCI)
- Multispectral skin imaging
Part A: SAD study in healthy subjects (cohort 1, 5 subjects) Cohort 1: 5 subjects, single i.v. dose of IMP761 or placebo (3:2). The first 2 subjects will receive IMP761 or placebo (1:1) as sentinel dosing, while the following 3 subjects will receive IMP761 or placebo (2:1).
Part B: SAD study in healthy subjects, KLH challenge (cohort 2-8, 60 subjects) Cohort 2-3: 5 subjects, single i.v. dose of IMP761or placebo (4:1). Cohort 4-8: 10 subjects, single i.v. dose of IMP761 or placebo (8:2).
Part C: MAD study in healthy subjects (MAD cohort 1-2, 14 subjects) MAD Cohort 1-2: 7 subjects, multiple (three i.v. doses of IMP761 or placebo (5:2). Investigational Medicinal Product (IMP)/placebo administration every 28 days; dose selection to be based on observed pharmacodynamic effects in part B.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing IMP761 and keyhole limpet haemocyanin (KLH) in people with Healthy, run by Immutep S.A.S. at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Occurrence of clinically relevant abnormalities in vital signs (time frame: From screening to the follow up visit after last treatment (up to 143 days)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026.
